Cannot create MQTT sensors 2022.10.2

Hello,
I recently update HA (Docker version) to 2022.10.2.
My MQTT sensors don’t work anymore.
Here is my configuration.yaml :

mqtt:
  broker: 192.168.0.182
  port: 1883
  username: xxx
  password: xxx
  sensor:
    - state_topic: "mst/chauffage/mst/temp/phenrysalle"
      name: "ch_temp_phenrysalle"
      unit_of_measurement: "°C"
      value_template: "{{ value_json.temperature }}"

Here is the log error :

Source: config.py:701

To make the HA update, I had to comment all the MQTT section in my configuration.yaml…
Can you help me on that ?
Thank in advance

My mistake !
The new MQTT configuration is for 2022.12.0 version !
